Payment Provider Migration Plan for Orders and Subscriptions

Payment Provider Migration Plan for Orders and Subscriptions

A payment migration is a controlled data and operating transition, not only an API replacement.

Decision boundary

A payment migration is a controlled data and operating transition, not only an API replacement.

Do not begin with a screen list or a vendor promise. Define the operating decision, the data that proves it and the person responsible for exceptions.

Requirements to confirm

1. Inventory active payment states and customer mandates
2. Run old and new reconciliation paths in parallel
3. Define support ownership for delayed callbacks and refunds

Common mistake

Treating a workflow as a set of fields usually creates a system that looks complete but cannot explain ownership, exceptions or acceptance. Keep each rule testable with representative records and real job roles.

How to start

Start with one bounded workflow, document assumptions and acceptance evidence, then expand after the first milestone is operated safely. See the related service and illustrative scope。
